HINGINGOF SHEET-METAL RECEPTACLESJ Specification of Letters Patent.

Original application filed May 11; 1917, Serial to. 167,941. Divided andthis application filed. June '11, 1917.

Patented Sept; 30, 1919.

Serial No. 174,054.

To all whom it may concern:

Be it known that I, GEORGE WILLIAM BERRY, a subject of 'the King ofEngland, and a resident of Lorna Doone, Old South Head Road, Rose Bay,in the State of New South tVales, Commonwealth of Australia, haveinvented certain new and useful Improvements in the Hinging 0fSheet-Metal Receptacles, of which the following is a Thisinventionrelates to improvements in the manufacture of coveredreceptacles in which the cover or lid is hingedly connected to the bodyof the receptacle, and particularly to receptacles in which the hingemembers are formed from and integral with the material of the lid andbody and pivotally connected without the aid of a Wire pintle ordinarilyemployed for this purpose, the hinge members being formed by passing thelid and body successively within the sphere of the operation of dies.

It is the object of the invention to provide an improved formation ofthe hinge members and of hingedly connecting a lid to a body whereby thehinging operation will be simply and economically performed in a highlyefficient manner and a strong and durable hinge will result.

The present application is a division of my co-pending application forpatent filed May 11th, 1917, Serial No. 167 ,9 11.

In the drawing accompanying and forming a part of this specification,Figure 1 is a perspective view of a lid and body having hinge membersformed thereon constructed in accordance with the present invention.

Fig. 2 is a perspective view of a lid and body hingedly connected by myimproved form of hinge.

Fig. 3 is a perspective view on an enlarged scale of a portion of thebody showing a hinge member when in hinge connecting position; and nFig. 4 is a perspective view on an enlarged scale of a portion of thebody showing the manner of pressing the bulbed tongues from the body.

In the embodiment of the invention shown in the drawing the body 5 ofthe receptacle is formed with bulbs 6, 7, these bulbs bi formed on thatpart of the s to ct institute the back, The

forming a depression or groove substantially to semi-circular shape incross section, as shown at 9, this depression being'formed by the samedies that forms the bulbs.

After the bulbs 6, 7 and the depression 9 are formed in the back of thebody, incisions 10, 11 are made above and below the bulbs therebyforming bulbed tongues, the inner ends of which are bent upward, asshown in Fig. 1 and Fig. 4.

The rim of the lid 12 is formed of greater depth at that part which isto constitute the back than at the front and ends of the rim, thisdepending portion being longitudinally creased or folded by dies alongthe lower edge to substantially U-shape in cross section, as shown at13. After the crease 13 has been formed a portion of the rim at andabove the ends of the crease are cut away as shown at 11, forming hingepintles 15 at the opposite ends of the crease, to be embraced by thebulbs 6, 7

The lid and body are now formed with the hinge members, as shown inFig. 1. To hingedly connect the lid and body, the body is placed overone side of a die with the pintles directly beneath the bulb tongues 6,7 when the top part of the die descends and presses the tongues back totheir original position with the bulbed portions thereof, engaging overthe pintles as shown in Fig. 2.

The advantage of slitting the material on the back of the body above andbelow the tongues and bending the tongues laterally instead of in themanner disclosed in my copending application above referred to, is thatthe tongues can be made very short and the pintles on the lid can bemore readily placed in position beneath said tongues almost vertically,thereby greatly facilitating the hingedly connecting of the lid andbody.

In order to make the bulbed tongues rigid and to prevent them beingpressed outwardly when. subjected to adverse strains a bulb or flute 3.6is themed at tltie base of each tongue after the tongues are moved toclosed position over the pintles. These flutes form buttresses which canbe of any suitable length and may extend from or pressed either inwardlyor outwardly to pror duce the result of stiffening the bulbed c tongues.

Having thus described invention, 1 claim:.-

. '1'. Theherein described improvement in hingedly connecting the lidand body of a receptacle in which bulbed tongues pressed 7 from the bodyengage over pintles carried '20 by the lid, of forming a fiute'at thebase oi the bulbed tongues transversely ofthe line of connection betweenthe tongues and the body when the tongues are bent to position to engageover the pintles to stiffen the co iu of this patent ma be obtained forThe flutes arearra-nged to bridge tongues to prevent the tongues frombeing pressed outwardly after being pressed to hinge forming position. rr 7 2. The herein describedimprovement in the formation of hingememberson the lid and body of a receptacle and hingedly connecting the lid andbody, consisting in forming a rimmed lid with a crease along the loweredge of a portion of the rim, cutting portions of the lid rim above andat the ends of the crease to form hinge pintles, forming bulbs with theinner ends open-on the back of the body, making incisions above andbelow the bulbs to form bulbed tongues and pressing said tonguesoutwardly, passing the lid pintles beneath. the bulbed tongues andclosing the tongues over said pintles, and simultaneously with theclosing of the bulbed tongues over the pintles forming a stiffeningflute at the base of each ,bulb to extend transversely to the line onwhich the tongues were bent for the purpose specified.
